Realty Income Corp is a publicly traded real estate investment trust that acquires, owns, and manages freestanding single‑tenant commercial properties leased on long‑term net‑lease terms, meaning tenants typically cover rent, taxes, insurance and maintenance. It operates primarily in the net‑lease segment of the commercial real‑estate sector, with a portfolio that spans retail, industrial, and specialty uses across the United States, the United Kingdom and several European countries. The company is one of the largest global net‑lease REITs, is a member of the S&P 500, and markets itself as “The Monthly Dividend Company” because it distributes dependable monthly cash dividends funded by the steady rental income from its diversified tenant base.
